[EXCHANGE API changes]

1) Termination of support for authentication method using fieldquery when generating JWT payload

• In April 2019, [JWT authentication method] (https://docs.upbit.com/changelog/open-api-%EB%B3%80%EA%B2%BD%EC%82%AC%ED%95%AD-%EC%95%88%EB%82%B4-%EC%A0%81%EC%9A%A9-%EC%9D%BC%EC%9E%90-423-1100) was added using fields query_hash and query_hash_alg.
• The existing authentication method using the query field will end support for service stability. Please change it to the authentication method using query_hash.
• For more information, visit Upbit Developer Center.

2)Termination of Content-Type support except for application/json

• Support for body parameters except for the JSON form of the POST API will be terminated.
• If you use other forms such as unlocked-form, please change them to JSON form.
• Requests that do not use the GET API and body parameters are not affected.

• Example
  • Before change: key1=value1&key2=value2
  • After change: {"key1": "value1", "key2": "value2"}
